Abstract

The invention provides a compound emulsifying agent for preparing an aqueous emulsion, comprising the following components in percentage by mass: 28%-40% of fatty alcohol-polyoxyethylene ether, 19%-40% of alkyl phenol polyoxyethylene ether phosphate or fatty alcohol-polyoxyethylene ether phosphate or kali salt of the alkyl phenol polyoxyethylene ether phosphate and the fatty alcohol-polyoxyethylene ether phosphate, 4.5%-10% of organic base and 19%-45% of emulsifying agent span. The compound emulsifying agent has the advantages of good popularity, easy preparation, stable property and high cost performance and is suitable for the parathion and the production of a plurality of pesticide aqueous emulsions.

Description

Technical field: [0001] The invention relates to a general-purpose composite emulsifier, in particular to a composite emulsifier for preparing a pesticide water emulsion. technical background: [0002] Water emulsion is one of the most environmentally friendly formulations of pesticides. A new pesticide formulation with water as an auxiliary material is an environmentally friendly green pesticide formulation that conforms to the development direction of the world's pesticide formulations. It is also one of the main pesticide formulations in developed countries abroad. Water-based preparations are highly valued by society today when environmental safety regulations are strict. In recent years, my country's water emulsions have developed rapidly. The varieties involve organophosphorus pesticides, pyrethroid pesticides, heterocyclic pesticides, etc. Water emulsions are liquid raw materials that are insoluble in water or soluble in organic solvents and special emulsifiers. After stir...
